Phytophthora perhaps?
Some in NZ still cropping after 30 years but smaller fruit.

I have a tree 45 years old. It has some shelter and good soil with a nice cool root run. Still bearing tasty good fruit well as it robs from a flower garden watered on one side

Does anyone know what is the disease or malady that causes feijoa trees to decline? . The symptoms are loss of older leaves and a general greying of the under surface of all the leaves. Sounds fungal but no reference to be found about this .

I have a Feijoa tree on my front lawn that is possibly coming close on 100 years old. It still produses delicious fruit and the biggest feijoa most people have seen.

Hi SRT

Normally, feijoa is tough like old boots but, just like any other plants sometimes they suffer pests and diseases most especially if they are not in their optimum health. Meaning us gardeners are sometimes neglectful of their needs assuming the 'she'll be right mate' attitude.

Firstly, irrigation - though its possible to grow feijoas in some areas without supplementary irrigation, however, managed irrigation is a must for a healthy and productive tree. The most critical time for moisture supplementation are: during flowering, later when the fruit starts to swell and post harvest for recovery.

Next up is fertilizer application. If your tree is already mature and fruiting the need to fertilize is much greater than younger trees. The first application should be around August/September when the temperature start to reach 8-10C to take full advantage of spring growth.The remaining application should be around autumn after harvest to assist fruit tree recovery. The ideal formula for fruit bearing feijoa trees should be less on nitrogen and more on potassium to avoid soft growth which are prone to frost damage during the winter season.

Thirdly is weed control. Feijoas struggle to compete with weeds and grasses. For healthy growth always maintain a weed free zone around your feijoa tree by mulching and controlling weed growth.

If you have regularly done the aforementioned crop management program and the tree is still struggling then its time to talk of pests and disease management. With regards to your tree i suspect that it is infected with anthracnose which affects leaves and blossoms of trees that appears as brown spots and later the leaves and blossoms die back and fall off. To control this disease spray your tree with liquid copper fungicide during winter and always follow manufacturers specs for greater success as well as for safety precaution.

Happy Gardening :-)
